DOUBLE-ENDED OR S-HOOK.

Specification of Letters Patent.

Patented. July 9,1907.

Application filed December 14,1906. Serial No. 347,865.

To all whom it may concern:

Be it known that I, EDWARD J ACOB HILL, a subject of the King of GreatBritain, and a resident of 11 Victoria street, in the city ofWestminster,-London, England, engineer, have invented a certain new anduseful Improvement in Double-Ended or S-Hooks, of which the following isa full, clear, and exact description.

My invention relates to an improved double-ended or S-hook, comprisingthe hook proper and a mousing link which is independent of and whollyseparable from the hook and can therefore be disconnected from either orfrom both ends of the hook at will, yet' without being necessarilydetached from the hook as a whole, so that both loops oi'the hook(instead of only one as usual) may be opened to permit of theirengagement with or disengagement from closed eyes, without the risk ofthe mousing link being accidentally lost. The hook of my invention isthus broadly distinguishable from other hooks otthis character in whichthe link is permanently attached to thehook.

In the accompanying drawings Figure 1 shows the improved S-hook in whatmay be termed normal condition, that is to say, with both its loopsclosed by the mousing link but not under tensile stress, while Fig. 2shows the hook similarly closed and under tensile stress. Fig. 3 alsoshows the hook under tensile stress, but with one of its loops open.Fig. 4 shows the hook with the mousing link engaged with one of theterminal hooks and in process of being engaged with or disengaged fromthe other terminal hook. Fig. 5 shows the preferred form of mousing linkand Fig. 6 illustrates a modified form of the same.

Similar letters of reference indicate corresponding parts in all thefigures.

The hook proper consists of a single length of rod or Wire bent to anearly closed S form or approximate figure-of-eight with its endsrecurved to constitute short open terminal hooks a a lying in the sameplane with the main loops A A and facing in directions opposite to oneanother. The mousing link B is preferably completely closed and of theoblong shape shown in Fig. 5, its side members crossing the waist A ofthe S hook at the opposite faces of the latter, and the bows b b of thelink being adapted to be engaged with the respective terminal hooks a aof the loops The internal length of the link B (Fig. 5) is made suchthat in order to permit of both its bows b b being engaged with ordisengaged from the hooks a a one or both of the outer or free limbs c cof the S-hook must be sprung slightly inwards towards the waist A asindicated in Fig. 4, the terminal hooks a a being preferably so placedthat the link B when thus engaged with both will cross the waist A ofthe S-hook obliquely as indicated in Figs. 1 and 2. When the hook as awhole is thus closed by the link B, it may be subjected to any degree oftensile stress (see Fig. 2) without either of the loops A A opening aswould be the case if the link B were disengaged from, say, one of theterminal hooks, as shown in Fig. '3 in the case of the terminal hookuThe transverse breadth of each loop A and A of the S-hook is madegreater than the internal length of the link B (Fig. 5) so that, whendisengaged from either of the terminal hooks a a (see Fig. 3) or evenfrom both of the latter, the link cannot become accidentally detachedaltogether from the S-hook; it being neces sary, in order to effectcomplete detachment, that the link should be first disengaged from bothhooks a a and then threaded over the entire length of the S-hook to thepoint of one of the terminal hooks a or (1.

It will be obvious that the link B may be of various forms. In Fig. 6 isshown a link which has only a single side member b, each of the endloops 1) 6 being separately closed and made of an internal lengthadapted to permit of its being passed over one of the terminal hooks aa? of the S-hook.

It will be obvious that the improved S-hook is capable of being appliedin a great variety of ways, and (among other uses) .is specially adaptedfor building up chains of indefinite length, each link of such a chainbeing capable of ready disengagement from the adjacent link on eitherside.

What I claim as new and desire to secure by Letters Patent is A hook,comprising an S-shaped hook of spring material and having the ends ofits tree limbs bent outwardly and approximately parallel with the saidlimbs to form terminal hooks facing in opposite directions, and amousing link upon the hook and adapted to close the loops of the Shook.
